u o t TO ALL WHOM IT MAY CONGERN:

Bc it known that I, THOMAS Unimet' Springlield, in the county of Keokuk,and State of Iowa, have invented a new und useful improvement inlagon-Bral@ Loek; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enahle'others skilledin the art to make and use-the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure l is front view or" my improved wagon-leek.

Figure 2 is a side view.

Similar letters of reference indicate like parts.

This invention relates to an improvement in the construction of locksfor operating the brake on a wagonwheel, and consists-in a lever,attached to a wooden block, for securing the lock to the side of awagon, and connected with an eccentric piece in such manner that whenthe lever is thrown back it draws the brake-lever bar and forces therubber or shoe against the wheel, and at the same time brings theeccentric piece into such` a position that it binds upon an iron segmentand lockslthc wheel. By a simple application ot' the hand to the lever,the eccentric piece is released from the segment and the brake-shoeremoved from the wheel. This contrivanee is very siniple,icheap, andeffective in its operation. It may be used on either or both sides of awagon, and is attached very readily.

A represents a flat wooden block for supporting the lock and fasteningwith screws or otherwise to the side of a wagon forward ofthe hindwheel. Upon the block,A, a straight iron lever, a, is pivoted at 011eend at or near a centre point of a thick iron segment-plate, b, to sweepevenly upon its circle. The segment-plate is made rough on the edge. Aniron eccentric, c, is pivoted to the lever a, and hung by a link-jointto a rod, (Z, that vextends up by the side of the lever a near to itsend, where it bends at right angles and passes through a slot,

c, in the lever ct, and has an eye or knob en its end to prevent it fromcoming out of the slot. The eccentric a is also made rough on the edgewhere it comes in contact with the edge of the segment-plate I). A rod,g, is also pivoted at one end to the lever a, to be connected at theother end with an ordinary wagon-bralc lever, as indicated in red lines.For the salie of illustrating the operation of my improved wagon-lock,the exhibit has a spiral spring on it instead` of the rod g, whichspring gives the necessary play to the eccentric c, and such as it wouldhave when connected by a rigid rod with the brake-lever on a wagon, bythe rod giving way under the v strain before the rubber or shoe is tighton the wheel.

To operate this lock thelevcr a is'thrown back to draw the rod g whenthe eccentric c bears upon the edge of the segincnt-plnte b, and by itspeculiar shape and position, in connection with the rod d, catches andbinds upon the plate in such manner that it cannot slip forward, andtherefore locks or holds the brake fast on the wheel of a wagon. Torelease the eccentricaI and unlock the brake, it is only necessary tobear on the lever a and at the same time raise rod al in the slot e. Thelock may he reversed for use on either side of a' wagon.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- The eccentric c, in combination with the rod d, theslotted lever a, and the segment-plate Z, forloeking a wagon-brake hymeans of the connecting-rod r/, constructed, arranged, and operatingsubstantially as and for thc purposes described.

THOMAS URIE.
